There seems to not be one specific version (and build) which works best for everybody. Given the multitude of different hardware configurations in use it's really a matter of finding the version (and build) which works best for you. It seems that each build has more or 'improved' drivers which has an effect not always to the liking of everyone.
Having said that I'd try the last build of TI8 (build 937) and see if it works well for you.

I have decided to go back to version 8 build 937, too.
I have completed 20 backup/restore tests and all works perfect.
TI 9.0 - always images are corrupted. I can't restore backup made with version 8 using version 9 rescue disc.

Nah, I am not so desperate yet to get my $30 back. I will keep a license to have a right to report every single problem to Acronis. At least they need to response to me as I am a licensed user.
If they keep saying rubbish then I raise a request for a refund.

Please accept my apologies for the delay with the response. I'm also really sorry for all the inconveniences caused by the behaviour of Acronis software.

However, I believe that our Development Team will do their best in order to fix all known issues as soon as possible.

If you encounter any problem while using Acronis True Image then please describe your issue in details starting new thread for each problem or bunch of a similar problems. We will certainly try to help you.
